Seeking Advice on Harley Davidson Evo Ignition Module

I’ve been having some trouble with my Harley Davidson Evo that I’d love some advice on. Recently, it seems like there’s been a bit of a hiccup with the ignition system, specifically with the ignition module.

I’m not entirely sure if it’s the module itself that needs replacement, or if there’s something else going on. Here are some details:

  • Model: 1995 Harley Davidson Sportster
  • Symptoms: Intermittent starting issues and rough idling
  • Previous Work: Just had the carburetor cleaned, so I don’t think it’s fuel-related.

Questions:

  1. Replacement Recommendations: Has anyone here had experience replacing their ignition module? Any brands you would recommend or ones to avoid?
  2. Compatibility: I’ve heard that not all ignition modules are compatible with every Evo model. How can I confirm that I’m buying the right one?
  3. Troubleshooting: Has anyone faced similar issues and solved them? What steps did you take to isolate the problem?

I’d appreciate any insights or experiences you have to share. I’m hoping to get back on the road as soon as possible! Thanks in advance for your help!

A good starting point is to check for error codes using a diagnostic tool. If there are specific ignition-related codes, it’s a strong indicator that the module may need replacement.
